Effects of pre-slaughter fasting on broiler welfare, meat quality, and intestinal integrity

The Brazilian Ministry of Agriculture (MAPA) regulations establish 12 hours as the maximum pre-slaughter fasting period for broilers; however, many processing plants have considered this time is not sufficient, and consequently return the birds to the farms, with consequent economic losses and welfare problems. Therefore, it is necessary to investigate the possible effects of longer pre-slaughter fasting times. The objective of the present study was to evaluate the effect of pre-slaughter fasting times longer than those established by MAPA on broiler welfare, breast meat quality, and intestinal integrity. Forty 42-d-old broilers were submitted to different pre-slaughter fasting times: group I: 6 hours, group II 9h, group III 12h, and group IV 15h. Bird...

Energy balance in the poultry-shed system and its influence on broiler performance
Provedor de dados: 70
Autores: Silva,Tatiana P. N. da; Pandorfi,Héliton; Guiselini,Cristiane.
ABSTRACT The objective of this study was to determine the energy balance of the poultry-shed system and its effect on broiler performance during the production cycle. The experimental design was completely random with sub-divided blocks. The blocks were composed of five different types of sheds and the sub-blocks of the evaluation times (00:00 h to 23:00 h), allowing an analysis of variance and a comparison between means with the Tukey test. There were no significant differences between the mean values of the exchanges of sensible, latent and total heat between the poultry sheds but the differences for the evaluation times were significant (P&lt;0.05). There was no significant difference between sheds 1 and 4 for broiler productive performance regarding...

GO AHEAD, COUNT YOUR CHICKENS: CROSS-HEDGING STRATEGIES IN THE BROILER INDUSTRY
Provedor de dados: 31
Autores: Maynard,   Leigh J.; Dillon,   Carl R.; Carter,   Joy.
Some suppliers of broilers without giblets (WOG) offer customers a choice between paying Urner Barry's WOG quote or a formula price based on futures prices.  From a buyer's perspective, the formula price examined in this study is second-degree stochastic dominant.  The formula price allows the seller to set perfect cross-hedges of WOGs with corn and soymeal.  Stochastic dominance and mean variance results suggested that the seller's dominant strategy would shift from the Urner Barry quote to the hedged formula price as risk aversion increased.  Input-based formula pricing may be usefully extended to other industries.

Natural shading and productivity index of broiler chickens
Provedor de dados: 70
Autores: Souza,Fernando A.; Milani,Adhemar P.
The appropriate use of natural resources in the design of broiler houses provides a reduction in farming operating costs and optimization of production conditions. Therefore, the natural shading around the broiler house can be an alternative for improving internal conditions of comfort. This study verified the efficiency of natural shading in the broiler productivity index (PI) in East-West oriented commercial housings. The PI of 32 commercial broiler houses in five flocks divided throughout a year was compared. The sheds had the same management, density and the same structural features, except from tree shading: on the North face; on the South face; on both faces and without shading. It was observed that broiler house in East-West direction with shading...

PRODUCTIVE RESPONSES FROM BROILER CHICKENS RAISED IN DIFFERENT COMMERCIAL PRODUCTION SYSTEM - PART II: IMPACT OF CLIMATE CHANGE
Provedor de dados: 70

ABSTRACT Broiler chickens are homoeothermic animals, i.e., animals capable of maintaining their body temperature within quite narrow limits; therefore, climate change poses a great challenge to poultry. With this in mind, this research aims to evaluate the performance of broilers submitted to different commercial production systems and exposed to different future scenarios, taking into account the climate change trends. To achieve this objective, we developed and validated a fuzzy model able to predict the performance of a broiler as a function of enthalpy along its life stages. This model was developed and validated in part I of this article based on experimental data collected for one year in three aviaries: conventional, negative pressure, and dark...
